Binding a TreeView to a collection of objects

through data binding. That is, I've got this collection of objects of the same class (currently stored in a ArrayList), and I want to display them in a treeview, so that when you expand them you can see the values of their attributes.

Hi,
I'm completely new to WPF (this week) and still grasping C# and .net as a whole.
I've created a User Control which I need to add (and be able to remove) multiple instances of into a vertical list. I've so far stuck this in a Listbox although I might change this later when I'm more comfortable.
So when I add the object I've created as a ListBox item it displays fine, but my issue is I need to able to delete items and add items and have those items auto update etc - so I'm guessing the WPF way to do things is to build a collection and have it bind
to the list box.
My question is this, what is the best type of collection to hold such objects. I've tried an Observablecollection so that I can monitor changes but when I give it a.Itemsource = Observablecollection it just presents me with a list of <Collection>.
Anyone any ideas?

Hi folks,
about 1,5 months ago I have set up a - 1 server - development environment for PS2007. I had installed all components on one Windows 2008 box. Everything worked fine, now I receive an error.
•MOSS 2007
•SQL 2008 SP1
•MOPS 2007 SP2
I have done the additional installation for the cube building part according to this page
http://technet.microsoft.com/en-us/library/dd285466(office.12).aspx
Microsoft SQL Server Native Client (sqlncli.msi)
Microsoft SQL Server 2005 Management Objects Collection (sqlserver2005_xmo.msi)
Microsoft SQL Server 2005 Backwards Compatibility Components (SQLServer2005_BC.msi)
Everything worked fine. Cubes were able to be built.. everything was good. In order to have Reports built I added
SSRS 2008
Reporting Services Addin for MOSS (rsSharePoint_x64)
Business Intelligence Development Studio (=Visual Studio for MSSQL)
No CUs have been added to this box.
NOW, Cube creation fails with the error:
ULS LOG:
[CBS] ProjectServerOlapCubeGenerator status: Analysis Services session failed with the following error: Failed to connect to the Analysis Services server <IPADDRESS>. Error: ActiveX component can't create object 08efbc13-299a-4abe-9021-c46887ca6915

Is there any way i can bind the sharepoint treeview navigation to the same datasource as the quick launch bar?
I'm trying to create a consistent navigation structure within a 4-site deep structure so the quick launch bar is rather clunky to use, but the treeview picks up on document libraries i don't want it to (i only want it to show subsites and pages).

We're having an issue with a TreeView hanging onto a viewmodel set that has been bound to it. We have a static treeview on the main window, and reset its ItemsSource to Nothing or a new viewmodel when new things need to be displayed. The problem seems to
be that it's hanging onto the first item that it was bound to, even after the ItemsSource is set to nothing. The connection seems to be through some strange unknown binding that's in the EffectiveValues collection of the TreeView.
I was able to repro this in a test project, so I'll post the simplified code:
TreeView templates:
<Window.Resources>
<HierarchicalDataTemplate DataType="{x:Type local:ParentViewModel}"
ItemsSource="{Binding ChildVMs}">
<TextBlock Text="{Binding Name}"/>
</HierarchicalDataTemplate>
<DataTemplate DataType="{x:Type local:ChildViewModel}">
<TextBlock Text="{Binding Name}"/>
</DataTemplate>
</Window.Resources>
ViewModel definitions: (Shared Function to generate the itemssource for the treeview)
Public Class ParentViewModel
Public Shared counter As Integer = 0
Public Shared Function GenerateViewModel() As List(Of ParentViewModel)
Dim pvm As New ParentViewModel With {.Name = "Parent" & counter} ' Unique name
pvm.ChildV

I have created a user control (supplierPicker) intended to allows a supplier database to be searched and a supplier selected. I want to be able to use this control in a number of other user controls, by binding the suppplierID property of the supplierPicker
to a supplierID property in a business object, which is set as the datacontext of the parent user control.
When I do this, and there is a supplierID specified in the business ofbject, the binding sets the supplierID in the supplierPicker control and it shows the correct supplier name in the textbox. However when the supplierID DependencyProperty is
changed from within the supplierPicker the newly selected supplier name is shown in the TextBox, but the SupplierID does not propogate back to the business object.
Other controls on the parent form work fine, so the binding to the business object seems to be ok.
Any pointers as to what I'm doing wrong here would be grately appreciated. This one has been driving me nuts for days!
Snipped code for the supplier picker:
public partial class SupplierPicker : UserControl, INotifyPropertyChanged
{
public static DependencyProperty SupplierIDProperty;
public event PropertyChangedEventHandler PropertyChan

My TreeView controls is rendering CheckBoxes on Leaf nodes. I want to bind to those nodes the ID of the underlying data item. I am not sure I can do this declaratively or if I need to hook up to the TreeNodeDataBound event. If the latter, how would I go about achieving this?

I have been trying to design a form, which uses a view model that contains an object array. I want to set up this form so that when the submit button is clicked, all the members of the array are updated. Here is my code:The class definition of the array element:public partial class luSubject { public string Name { get; set; } public bool FilledName { get; set; }public in MasterSubjectId{get;set;} public luSubject() { FilledName = true; } }This is the view model I used for the form:public class TestModel { public luSubjects[] Subjects; public int[] MS { get; set; } public SelectList sl { get; set; } public TestModel() { Subjects = new luSubjects[3]; for (int i = 0; i < Subjects.Length; i++) &n

This is my experiences. I can bind the DataGridView using DataSet and Collection.
1st expericence, If using DataSet, my DataGridView
have an empty row at the last row (have to set AllowUserToAddRows Property to False). If using Collection, my DataGridView
do not have empty row at the last row.
2nd experience, I know how to rebind the DataGridView using DataSet. But I
dont know how to rebind the DataGridView using Collection.
My collection as follow,
private Collection<MasterAgentCompany> myDGV = new Collection<MasterAgentCompany>();
private BindingSource bindingSource = new BindingSource();
dgv1.DataSource = bindingSource;
bindingSource.DataSource = myDGV;
dgv1.Refresh();
/*THIS CODE IS OK ON 1ST TIME LOAD*/
/*IF I'M CALLING THIS CODE AGAIN, MY DATAGRIDVIEW NOT REFRESH THE NEW RECORD*/
I'm looking the right technique to rebind DataGridView using Collection
I'm stuck. Really looking for help

I was wondering if i could use a TreeView to display data from 2 separate collections where both collections are members of the same object. For example i have a view model that has 2 observable collections:

Brands

Models

Each model has a property Brand which specifies the brand for each model. What i want to do is bind the first level to the Brands collection and the second level to the Models collection and specify a filter.

Hello,
I am using Object as the data source to my Listview and trying to display data in a Hierarchical manner. I am not able to figure out how to bind these objects to my listviews. Below pasted is the code.
I am trying to place Listview inside another listview, inside another listview inorder to display data in a hierarchical manner. Any help is very much appreciated.

I'll first explain a bit what I'm doing so that the code paste will make a bit more sense. I'm creating a circular menu control for Microsoft Surface (this question is far from Surface specific though, but otherwise this type of control wouldn't make sense
:) ), it has some 'pieces' which are all buttons. I've created a 'Menu' control which contains the menu items, I made a custom control for these items (so I could add them to the menu within XAML), and I made a Button control which actually does the drawing
of the path etc. I've done this in this specific way because the angle of the button's path will depend on the number of pieces within the menu. Anyway the above all works fine and dandy and I'm happy with the result. However now I'm trying to get all of this
to work.

What I want to do is to use MVVM in my application and bind the MenuItems to a command in my ViewModel. So I have an AdminToolbox which is a view containing the menu and there's an AdminToolboxViewModel which is the ViewModel with the command and the items
that I'd need to bind to my menu to create the menu items.

I'm not too familiar with Hierarchal DataTemplates yet, but here's what I want to do.

I have a message box that has a small expander on the bottom with a treeview inside. I want to hook the treeview up so that during runtime when an error occurs it can be caught, loaded into this treeview and displayed (including all the inner exceptions).

How would I go about doing this?

I'm fairly familiar with wpf and I can get everything into the message box correctly it's just the final display that I can't do yet. Also, I'm using VS 2010 Ultimate Beta 2. Thanks in advance!!
